For the first few years that they know each other she’s like oh I remember my past life too much to like him. But then when she talks to the mage tower leader he tells her how Grana’s body is ALSO her even though she remembers her past life. So after she accepts that she’s Grana she starts treating herself more like her own age instead of her past life. She still only starts falling for the ML once they’re getting to adulthood. Plus from the way they talk about her past life she was very heavily stunted because she wasn’t taught to read or write, and her life was basically decided for her. So like 80 years of solid handcrafting and having a child or two in the middle of it and zero life experience outside of that
TLDR No because she’s not a grandma reincarnated as much as she is a girl with some memories of her past life.
thank you for the clarification, but she still carries on her past memories and experiences of her whole past does she not? so it’s not really a rebirth either since I was informed that it’s still her past past life and not a new life idk to me its still unsettling as she holds the mindset of her grandma-self if you get what i mean.

i read a comment saying that the 89 yr old grandma has an attraction to the ml whos as old as her grandkids??? IS SHE NOT A PEDO WHAT IS GOING ON
